Deploying a WinRT Application on Multiple Devices

Question

If you are creating an application against WinRT, can you deploy it on any device or you need to have several assemblies (one per platform), how are you doing right now?

Answer 1

WinRT applications created in JavaScript or C # will be deployed unchanged on any Win8 machine. This includes Arm devices on Stephen Sinofsky's label. Applications written in C ++ should be compiled for the appropriate architecture (x86, x64, Arm), but should not require any modifications to the source.
